SPECIFICATION forming part of Letters Patent No. 716,539, dated December23, 1902. Application filed January 26, 1901. fierinl No. 44,878- lNomodel.)

To (1Z5 whom it may concern:

Be it known that I, IRWIN J. FRENCH, a citizen of the United States,residing at VVashington, in the District of Columbia, have inventedcertain new and useful Improvements in Circulating Water Systems, ofwhich the following is a specification.

My invention has for its object to make use throughout a heating systemof single pipes, valves, connections, and radiators, and this I secureby the use of parts each with a vertical partition, so as by theconnection of these single elements to secure a complete continuousoutflow -channel and a returnchannel without the employment of anyindependent pipes or parts at any point of the system.

In the accompanying drawings, Figure 1 is an elevation, in part section,illustrating my system as embodied in a hot-water househeating system.Fig. 1 is an elevation, partly in section and partly broken away and ona larger scale than Fig. 1, to more clearly show the continuity of thepartitions in the several parts of the piping. Fig. 2 is a perspectiveView illustrating the construction of the main straight-pipe members.Figs. 3 and 3 are views in perspective and section of two of the bends;Fig. at, a sectional view of one of the radiators; Fig. 5, a sectionalplan of one of the valve devices; Fig. 6, a section on the line 6, Fig.5. Fig. 6 is a longitudinal sectional elevation of the valve devices;Fig. 7, a sectional perspective view of one of the branches; Fig. 8, asection showing a coupling; Fig. 9, a section showing the Y forconnection with the steam and water spaces of a boiler; Fig. 10, aperspective sectional view illustrating the arrangement of partition inanother form of bend.

The straight main members a consist each of a pipe, preferably ofwrought-iron, with a transverse longitudinal partition 1, which isvertical, whatever the arrangement of the pipe.

The pipes a are threaded at the ends for union by the usual couplings,and the partition 1 is extended to the ends of each section, so thatthose of adjacent pipes will abut with packings between, if desired.

Each bend c is divided by a partition 2,

which is parallel to either the plane or curve of the bend, as in Figs.3, 3, the ends of the bends threaded, and the partition extending nearlyto the ends. The branches cl have longitudinal partitions 3 in the bodyportions 4, which partitions 3 extend also in verti' cal positionthrough and divide the bends 6, Fig. 7.

Each valve-casing c has a central casing 8, communicating with the bodyportions 9 9, each with a vertical partition 10, said casing extendingdownward, forming a pocket to receive a flat valve f, which may beraised to cut off passage through the valve or lowered to restore it,and when lowered a cross blade or portion 12 of the valve-stem forms,with the partitions 10 10,a continuous division through the valvestructure. A neck 14 is shaped to form a pocket to receive the part 12of the valve-stem when raised, the stem 17 extending through thepacking-cap 18 and being provided with a handle.

Each radiator g is divided by a vertical partition 19, which extends toand divides the port (13, so that water passing in at one side of theport flows into one chamber and at the top to the other and then outthrough the other side of the port. The above-described parts are unitedaccording to the necessities of the construction, one arrangement beingshown in Fig. 1, and when thus united form a duplex structure throughoutthe singlemember system, each member being in external shape like onemember of an ordinary double-pipe system, but serving the purposes oftwo members, one a delivery and the other a return member. Thus theweight of the structure is greatly reduced, the number of joints is justone-half those ordinarily required, dividing the labor and time forcutting threads and couplings, and greater com pactness is secured withless loss of heat by radiation from the pipes.

In Fig. 10 is shown the arrangement where the branch arm extendsfrom-the .top of a horizontal pipe. In this case the partition twists,as shown, so as to be vertical at the termination of each part of thestructure.

In some instances the coupling 12 may have a partition, said couplinginternally threaded at the ends and the partition extending only to thethreaded portions, as shown in Fig. 8; but where any of the members arethreaded externally the partition extends to the ends. The portion 12 ofthe valve device before described may be only as thick as the thicknessof the valvef; but preferably it is formed into a wide blade, as shownin Fig. 6, so that when the valve f and part 12 are raised the removalof the part 12 will leave the opening between the inner end of thepartition 10 and the valve unobstructed, and the water can circulatefrom one passage to the other, as indicated by the arrows.

By the use of pipes and fittings with partitions arranged vertically, asset forth, there is secured a one-pipe system throughout that is, thereis no part of the system 'from the boiler to the radiators where it isnecessary to use crossed pipes or two separate pipes, and the necessityof employing castmetal pipes between the fittings is avoided, so thatthe horizontal and vertical piping throughout may be of wrought metal.Further, with horizontal pipes having vertical partitions a singleopening at the upper or lower side serves to connect with both sides ofthe partition, while with a horizontal partition there must be bothupper and lower openings and outside separate pipes and fittings.

Without limiting myself to the precise construction shown, I claim- 1. Aheating system, consisting of radiators, a single main supply and returnpipe, and single-pipe connections between the main supply and returnpipe and the respective radiators, all having partitions and connectedto each other in such manner that the partition of one will form apractical continuation of the partition of the other to which it isconnected, substantially as set forth.

, 2. In a heating system consisting of radiators, a single main supplyand return pipe, and single-pipe connections, between the radiators andthe supply and return pipe, a branch piece consisting of a body-sectionhaving a partition and forming part of the main supply and return pipeand a lateral extension also having a partition forming a practicalcontinuation-of the partition of the bodysection, said lateral extensionforming a part of the single-pipe connection between the main supply andreturn pipe and a radiator, substantially as set forth.

3. A valve device consisting of the body portions 9, 9, with separatedpartitions 10, 10, said body portions each having an upwardly and adownwardly extending pocket between the opposing ends of the partitions,a valve movable between the partitions, said valve having two blades atright angles one above the other, one of said blades being movable intoand out of one pocket and adapted to fill the space between theseparated partitions, and the other blade being movable into and out ofthe other pocket and adapted to close communication between the bodyportions 9, 9, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
